MONITORING OF INDUSTRAL SLENDER STRUCTURES

Monitoring of industrial slender structures (engineering structures) has gross significance because a potential breakdown e.g. of industrial chimney usually suddenly stops the whole production process provided by this chimney. Slender structures should be subjected to constant measurements not only at the erection stage but also in the course of exploitation. Gross significance is placed also on inventory measurements which provide information about a current condition of the investigated structure and are the grounds for further monitoring and repair works.

Factors causing slender structures to deflect.

One of the key geometric conditions to be met by slender structures is the axial verticality condition. Any deviations from this condition can be an outcome of the following factors:

errors in construction and land survey performance at the construction stage

activity of fumes and weather conditions causing the structure to weaken

unevenness of ground settlement under the foundations

wind pressure (side pressure and Karman's whirl)

thermal gradient (single-sided heating of chimney core by solar rays)

Slender structure subject to monitoring:

industrial chimneys

chimney coolers

radio and television towers and masts

observation tower

lighthouses

bridge pillars

windmills (wind power plant)

other slender structures

Monitoring verticality of slender structures offered by HAVEC Engineering covers both classic measurement methods and a 24/7 supervision using GPS technologies (in case of structures with gross production and construction impact).

Hot kiln alignment - the main area of our actions shall be to conduct mechanical inspection and to specify activities (regulations, exchanges, repairs, modifications, etc.) which should be performed to attain and maintain high effectiveness of the rotary kiln's operation.

We developed high precision measurement systems to allow to monitor current status of equipment and to plan maintenance activities. Hence, malfunctions and breakdowns can be reduced both in respect of their intensity and frequency.

We provide a wide scope of measurement services addressed to many industry branches. Highly precise measurements are the starting point for analyses and regulations supporting the work of machinery and equipment.
